I don't here such a 'ping' on all patches, but I do recall having
had hard times trying to get a smooth sounding attack, despite
sufficiently long attack times.

When starting yosh without any instrument/parameters, there
are clicks/plops/pings on note on. Not surprising of course,
due to the short default amplitude-attack times and near sine
default waveforms.
What I do notice is that for SUBsynth, increasing attack time to
a value of ~10 is sufficient to remove note-on clicks for even
moderately low frequencies, as should be expected if the unit
is [ms]. For ADDsynth and PADsynth in contrast, a value of >35
just barely silences the somethat 'plop'-like attac sound.
The same for release times.
Naively asking my ears, I'd say those plops are not tied to the
attack ramp of the env, the ramp just decreases the volume of
some plop, irrespective of the note frequency.

I find this not to be audible (or perceived as part of the
characteristic attack spectrum) for most patches with
significant HF content.

This is no different in Zynaddsubfx.
Not sure about any repeat echo.

best,
